Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. Connectors plug directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.

Installation
This custom-fit T-connector plugs into your vehicle's wiring harness. The connection point for the 4-way tow harness is located behind the interior trim panel in your rear cargo area. Once you've plugged in the converter, insert the included 10-amp fuse into the integrated fuse holder.
Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

I was able to replace an aged five-pin connector on a boat trailer I just purchased with this harness. It was quick and easy and a solid value priced product. Super happy with my purchase!
I used this harness to adapt the existing trailer wiring on my 2023 Hyundai Tucson Hybrid Limited to my trailer. The Tucson Limited has the tow package, which provides the manufacturer's wiring harness routed to the rear underside of the vehicle. I simply plugged this T-Connector in to the existing Tucson harness, then routed/fastened the connector near the trailer hitch. It worked perfectly and was very easy to install in a few minutes. I could have installed in less than 5 minutes, but I tried several different routing methods to make it the neatest possible installation. THIS is how all aftermarket equipment should work!

Still happy with this harness and have not had any issues works great.
This harness is not compatible with the 2025 Hyundai Santa Fe although it is recommended when purchasing a hitch. I didn’t realize it until after I checked out, tried to cancel the order but it was already processed. Was able to return but had to pay for return shipping. Partially my fault for not verifying compatibility, partially e-trailer’s fault for recommending on check out. Had to buy the OEM harness which you have to get from Hyundai directly.

We show the # CU94FR as a fit up until the 2024 model year. For a 2025, you'll want to use the # C48RV which will be available very soon....
Install was straight forward. Took me a little over 1 hour to install the hitch and wiring harness. Price was great. The dealer wanted 1100 dollars.etrailer was 300 dollars.

Hitch is working as designed. No problems at all.
This wiring was ridiculously easy to install. Etrailer videos always helpful. I have purchased 2 hitches and wiring harnesses from etrailer and have always been 100% happy!

The Curt T connector wiring harness is performing well. It's easy to install and is a good product.
I was able on Hyundai site to find out that all 2021-2023 Santa Fe vehicles have the trailer tow package. If in doubt just check your engine fuse panel as there is a 30 amp trailer fuse installed. On my PHEV my son was able to reach into the panel and plug the etrailer wire loom into the towing OEM connection. Installed the wire loom in 15 minutes. Was easier than the etrailer video showed.
I'm sure glad I bought the wireing harness along with the trailer hitch. It fit perfectly and made the hook-up a lot easier. A year later now, lots of use, and it still works perfectly.
I was very happy with the person who answered the phone. They were very knowledgeable. They knew what they were talking about. I got my product and it went in as easy on the installation as they said it was going to good job thank you.
Easy plug and play for my utility trailer. Fast delivery and excellent customer service.
Phenomenally simple and easy to install on my 2024 Hyundai Tucson SEL. The entire installation took exactly 6 minutes and 32 seconds. Yes, I timed it. The kit comes with everything you need for a quick installation. The unit worked perfectly when tested on my trailer. I’ve always trusted Curt items and this is no exception.

Still going strong after a year. This is a far better application than factory installed parts. I’ve had both and will continue to use Curt instead of ordering factory parts. Incidentally, the part and wiring harness and 14 the price of the factory set and twice the quality.

Easy install on my Hyundai Tucson Hybrid. etrailer videos are a big help.
Worked perfectly and was the correct fit for my vehicle. Wire harness matched right up with the OEM wire harness.
YouTube makes it look real easy to install, and it is, provided your attachment nuts rent full of rust, and you have a vehicle lift. Doing it with car on ramps and on your back is more difficult but doable. Follow the instructions and the installation is straight forward. The same applies with the wiring harness. In general, a very good product, well built and rugged. I’m by with it.
etrailer makes the install flawless because of support before and after the sale. The videos that cover the install made it so easy. Previously I purchased the Curt III hitch and the video was perfect.
Great company and very competitive pricing
Tip I put the wiring harness in 1/2” tubing along the route to protect from any chafing and used tie wrap to secure. I used JB Weld yo epoxy the bracket to hitch as there were no holes to secure bracket. Solid.
The instructions could have been better. My 2023 hyundai hybrid premium required an inline 15 amp fuse to work and the instructions did not explain this.
Great customer service. Thanks for all your help
This plug and play harness is So Easy to install
Love it and well worth the money spent.
Thanks to Joanne K at etrailer who helped me with my purchase over the phone. I also purchased the connector and a Curt no show hitch from her.
All were great.
Super simple plug and Play. Loved it. Didn't have to run wires all the way up to the front of the car. The plug and Play feature was excellent
Both items work great and easy to install following the videos provided on etrailer
Easy installation
This was a plug and play installation, very straight forward and easy. etrailer does a good job matching you up with what fits your vehicle. This is my second time buying from them and both experiences were very good, highly recommend.

Plug and play then off to adventure! What are you going to be towing, James?
Shipped the wrong part. I sent a screen shot of the part on your website stating the part would fit my vehicle. It did not. Was told I could return it for a fee even though it was your mistake. Return shipping label was never sent. Very disappointed.
Your company is great.... However, UPS delivered the packaged looking like this. Good thing nothing was missing or damaged See PICS
